wl1271: Indicate disconnection on hardware failure

In the event of a hardware failure, reconfiguring a live connection back
with the wl1271 chip does not work as expected. The chip has management
features which require setting up the association from scratch to work
correctly. To ensure this is done every time, in managed mode, when associated,
indicate connection loss to the mac80211 before asking to reconfigure the
hardware.
